In the accompanying drawings I have show n a spinning or twisting machine in which separate direct electric motor drives are providedv for 'the upper and lowei` decks of spindles and .their take-up mechanisms,V

said drives 'comprising broadly upper and lower electric motors and their spindle driv- I0 The frame of. the machine includes the img means and more specifically comprising front end frame 1 and the rear end frame 2,l

which frames are suitably connected by the longitudinal spacing bars 3. The frare 1s shown as supporting upper and lower decks of s pindles`4 and 5, respectively. The `winding roll shaft for the upper take-up mecha-nism .is denoted by '6 and the winding roll shaft for the lower take-'up mechanism by 7.

The'direct motor drive for the upper and lower decks o f spindles and their take-up mechanisms comprises upper and lower electric dmotors 8 and 9, respectively, mounted on the machine frame exterior to the front end thereof. In the present instance these motorsare shown as being carried by'upper and lower-bracl5ets 10 and l1, respectively, projecting outwardly from the front end frame 1. These motors are located between the'uppe'r and lower decks of spindles in vertical alinement and' in close proximity to each other, the upper motor 8 having its shaft 12 proj ecting a short distance upwardly beyond the motor and the lower motor 9 having its shaft 13 .projectinga short distance downwardly beyond the motor.

The short upwardly vprojecting shaft 1.2 of

the upper member 'is rovided .with a pulley 14 which drives the be t 15. This belt in turn drives the upper deck of spindles 4:. Similarly the short downwardly projecting shaft 13 of the lower motor 9 is provided with a'pulley 19 which drives the belt 20. This belt in turn drives the lower deck of spindles 5'. The rear end of the belt 15 passes around a pulley 16 of the upperfbelt tension mechanism, which pulley is provided' with a suitable guard 17. Similarly the rear end of the lbelt v20 passes around the pulley 21 of the `lower belt tension mechanism, which pulley is provided with a suitable guard 18.

As the upper and lower belt tension mechanisms are constructed, arranged and operated in the same manner, the up er belt tension mechanism only will be specifi The upper belt tension pulley 16 is carried by a vertical shaft 22 which is hung in suitable upper and'lower bearings 23 and 24, respec- `tively, carried by the upper member 25 of a 33 is gui-ded in its movement by an idler pu in suitable bearings in the side of the housing' y 27 the outer end of which cross shaft is provided with a pulley 32 to which is attached one end of a strap 33,`the other end of which strap is attached to a weight 34. This stra ley 35.

The means for driving the upper winding roll shaft 6 of the upper take-up mechanism from the belt tension pulley 16 is constructed,.arranged and o erated as follows:

The vertical sha t-22 of the belt pulley 16 is provided at its upper end within the member 25 of the sliding support with a spiral gear 36 which meshes at all times with a spiral gear 37 which is slidably interlocked by means of a spline 38, with arearwardly projecting shaft 39,said shaftl being rotatably mounted in suitable bearings in a hub 40 of the gear casing 41 secured to the rear end frame 2 of the'machine. A suitable guard 42 carried by the uppermember 25 of the slidable support surrounds the shaft 39.

This shaft 39 is provided with a pinion 43 within the gear casing 41, which pinion meshes with a. gear 44 rotatably mounted on a stud shaft' 45 carried by 'the gear casing 41. A pinion 46 is rotatably mounted on the -stud shaft 45 and fixed to the gear 44, which p'inion 46 meshes with a gear 47 carried by the inner end of a shaft 48 within the gear casing 41, which shaft is mounted `in suitable bearings in a hub 49 projecting rearwardly from the ar casing 41 through the rear end frame 2. 4e rear end of this shaft 48 is provided with a pinion v5() which meshes with a gear 51.

rotatably mounted on a stud shaft-52 carried by an arm 53 which is rotatably ad'ustable on the hub 49 about the axis of the s aft 48. A gear 54 which is also rotatably mounted on the stud shaft 52 is fast to the gear 51. The

arm 53 may be adjusted rotatablyto any po-v sition and there secured as, for instance, by the-bolt and nut 55,i 56. The stud shaft 52 is radially adjustable along a slot 57 in the arm 53 and may be secured in its proper adjustment by the nut 58. The. gear 54 meshes with a gear 59 fast on the upper winding roll shaft 6. A

A changa'gea'r arrangement may be provided between the' shaft 6 and the shaft 48 as, for instance, by making the gears 51 and 54 on the stud shaft 52, change gears.

Pmedingto describe the upper and lower traverse the upper traverse bar is denoted by 60 and the lower traverse bar by 61. Theirmspedve cams are denoted by 62 and 63. These traverse cams are each adapted to impart a reciprocating motion to two traverse bars.

As both of the traverse cams are driven from their windin roll shafts by quite similar means except or a slight modification in the driving of the lower traverse calm, one only of these mechanisms will be specifically described, namely, thelower one.

The lower Winding roll shaft 7 is provided at its front end just inside the. front end vframe 1 with a' spiral gear 64 which meshes with a spiral gear 65 onthe upper end of a vertical shaft 66 rotatably mounted in suitable brackets 67, 68 rojecting rearwardly from the front end rame 1. The lower-end of' this shaft 66 is provided with-a spiral gear 69 y which meshes with a spiral gear 7 0 on the rear end of a short rotary shaft 71, the front end of which shaft is provided with a pinion 72 located within a gear casing 73. This pinion 72 meshes with a gear 74 rotatably 63. This gear 79 and the cam 63 are permitted f a limited longitudinal movement-on the axle 80. The outer f a'ce of the gear 78 is provided with a cam 82 which engages a cam 83 carried on the inner face of--the gear 79 as one of these gears 78 or 79 is provided with `a lesser number of teeth thanthe other gear and, as both of these gears are meshed with the Wide face.

pinion 77, one of the gears 78, 79 will travel faster than the other gear, thereby causing the cams 82 and 83 to travel on each other and thereby constantly change the position of the cam 63 bodily. f

,The lever for reciprocating the lower traverse bar 61 comprises 1an, uprising arm 84 and a depending arm 85, said lever being pivotedat 86 to a bracket 87v projecting forwardly fromthe front end frame 1. lThe lower arm of this lever is provided with a stud or roller 88 arranged to engage the face of the traverse cam 63. The means which is shown for holding the stud or roller l 88 against the face of the camand -for yieldingly holding the cam at the limit of its rearward bodil movement to keep the cams 82 and 831of t e gears 78 and 79 in engagement with each other, is constructed, arranged and operated to take care of the traverse bar reciprocating levers for both sides of the machine as follows:

A pin 89is screw-threaded into the outer end of the axle 80, which pin is provided at its forward end with a suitabl handle 90 for turning the pin in the said ax e. yoke CII vers.

` pressingthe -yoke yieldingly inwards along the pin 89, a wearing plate 93 being preferably provided between the inner end of the spring and the yoke. It will be seen that the tension of this spring 92 may be readily adjusted to obtain the required pressure by screwing the vpin 89 inwardly or outwardly.

The only difference in the traverse cam mechanism for the upper traverse bars 60 is that the upper winding roll shaft 6 carries the pinion 72, the vertical shaft 66 and its gear connections being unnecessary.

From the above description it will be seen that the machine is well balanced as to WeightA by the mounting of the motors ,andtraverse cam mechanisms on the front end frame, and

a mounting of the belt tension mechanisms and their driving connections with the twist mechanisms on the rear end frame. This arrangement leaves the spindle space between shaft, is driven from the belt tension pulley and whereby a change speed mechanism may be readily included for securing the desired speeds in a very simple and effective manner.

Novel means have also been provided whereby the. traverse mechanism may be driven from the winding roll shaft of the take up mechanism at the front end of the machine by very simple and effective mecha-l msms. .A Y y It is obvious that various chan ves ma be resorted to in the form, constructlon an aring between the end frames, a ear connection, including a change gear, tension pulley and winding roll shaft at the rear end frame, and a gear connection between the winding roll shaft and-traverse cam shaft at the front end frame.

3. In a spinning and-twisting machine, a winding roll shaft, a'traverse cam shaft, and a train of' gears operatively connecting the two shafts at the front end frame of the machine, said train of gears including a vertically disposed shaft mounted along the inner side of the front end frame.
